Determining transformations for anatomically aligning fractured bone fragments

摘要

Computer implementation methods 200 and devices for determining transformations for anatomically aligning broken bone fragments are provided. An image of the broken bone of the subject is acquired (202). The bone is broken into two or more pieces. The corresponding unbroken bone model and at least one parameter are obtained. At least one parameter defines one or more variants to the model that are allowed when fitting a portion of the model of unbroken bone to the corresponding piece of broken bone (204). Based on at least one parameter, a portion of the unbroken bone model is fitted to the corresponding fragment of the broken bone (206). A transformation is determined to anatomically align the broken bone fragment with the corresponding part of the model (208).
